Femara Overview

Updated: 

Femara is a prescription medication used to treat breast cancer in women who have gone through menopause. Femara belongs to a group of drugs called aromatase inhibitors. It works by decreasing the amount of estrogen produced by the body, which slows or stops the growth of some types of breast cancer cells that need estrogen to grow.

This medication comes in tablet form and is usually taken once daily, with or without food.

Common side effects include nausea, hot flashes, and night sweats. Femara may cause drowsiness. Do not drive or operate heavy machinery until you know how this medication affects you.

Femara and Pregnancy

Tell your doctor if you are pregnant or plan to become pregnant.

The FDA categorizes medications based on safety for use during pregnancy. Five categories - A, B, C, D, and X, are used to classify the possible risks to an unborn baby when a medication is taken during pregnancy.

Femara falls into category X. It has been shown that Femara may harm the unborn baby. There are no situations where the benefits of the medication for the mother outweigh the risks of harm to the baby. These medicines should never be used by pregnant women.
